Signs of a hidden Planet Nine in our solar system may be an illusion
Hints of the remote planet, also called Planet X, relied on clumped up orbits of bodies beyond Neptune. A new study suggests that clumping doesn’t exist.

Let’s learn about the moon
The moon is Earth’s nearest neighbor, and its gravity helps stabilize the planet’s climate and creates the tides.

Scientists Say: Planet
Planets have to orbit a star, be big enough to form a sphere and keep other objects out of their path around their star.

Rogue planets wander the galaxy all alone
Some planets don’t orbit stars. They were kicked into space long ago. The newest, smallest one found is only about as massive as Earth.

Meet ‘Pi’ — a new Earth-sized planet
Searching through data from NASA’s K2 Mission, researchers found a new planet. Some call it K2-315b, others smile and refer to it as “Pi Earth.”

Jupiter may have ‘sprites’ or ‘elves’ in its atmosphere
This is the first time that scientists have seen hints of these weird side effects of lightning storms somewhere other than on Earth.

There’s water on sunny parts of the moon, scientists confirm
The new observations were made by a telescope on board a jet in Earth’s atmosphere. They confirm the presence of water on sunlit areas of the moon.

Let’s learn about Mars
Traveling to Mars offers many challenges, including life without gravity, cosmic rays and communication delays.
- Physics
Scientists Say: Gravity
Gravity is a fundamental force that attracts objects with mass to other objects with mass. It decreases with distance.

Let’s learn about space robots
Space robots can take pictures of other planets, analyze samples of their surface and even peer into their interiors.

Saturn’s moon Titan may host lots of dried lakes
Suspicious spots around the moon’s middle could be the beds of ancient lakes. If so, this might solve a 20-year-old mystery.

Let’s learn about exoplanets
Exoplanets are planets outside of our solar system. Scientists are finding out more about them than ever before.
